HUDSON, Wis. (AP) -- Jurors in western Wisconsin say a father had a mental defect but is still responsible for killing his three young daughters last July.

Aaron Schaffhausen pleaded guilty last month to three counts of first-degree intentional homicide in the deaths of 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia. But he argued he was not responsible because of a mental illness.

Jurors deliberated for about 3 1/2 hours before reaching their verdict.

During closing arguments Tuesday, prosecutor Gary Freyberg said Schaffhausen was in control of his actions and was a mean, callous person -- but not legally insane.

Defense attorney John Kucinski argued Schaffhausen has a rare mental disorder, rooted in a deep dependency on his ex-wife.
The jury found he had the capacity to know what he did was wrong.
